Procedure:
1. Place ½ cup of vinegar in the cup.
2. Add 1 tablespoon on baking soda.
3. Record your observations.
(Observed a bubbling with a rising of the liquid which
was carbon dioxide escaping)

Questions:
1. Write the balanced equation for the first step in the reaction between vinegar and baking soda, with carbonic acid (H2CO3) as a product. What type of reaction is this?
( HC2H3O2 + NaHCO3--->NaC2H3O2 + H2CO3 ,
which is double replacemtent...is this correct?

Need Help with the rest.......

2. Write the balanced equation for the second step in the reaction, the liberation of carbon dioxide from carbonic acid. What type of reaction is this?
3. Write the combined, balanced equation for the complete chemical reaction between vinegar and baking soda.
